Figure 3. Stereo view of a modeled structure of the
PGA-octagalacturonate complex. The electrostatic potential is
drawn at the solvent accessible surface of polygalacturonase
from -9kT/e^ - (red) to +9kT/e^ - (blue) and the substrate is
represented with a space-filling model. The N terminus is on the
top and the C terminus on the bottom. The unbent substrate spans
the binding cleft that is formed by the protruding loop regions
T1 (left side) and T4 (right side). The Figure was produced with
GRASP.[57]
